DEVICE FOR OPENING EGGS.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed November 13, 1915. Serial No. 61,218.

To all whom it may concern:

Be it known that-I, SAMUEL Mamiowrrz, a subject of the Emperor ofAustria-Hungary, and resident of the city of New York, in the county ofNew York and State of New York, have invented a certain new and usefulDevice for Opening Eggs, of which the following is a specification.

This invention relates to a device for opening eggs, and its principalobject is to provide convenient means wherewith a boiled egg may beopened in a manner other than by fracturing the shell thereof, ascommonly resorted to heretofore, and wherewith the insanitation andinconveniences incident to opening eggs by fracturing will be prevented.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a general plan view of thedevice, a portion of which is shown removed for convenience ofillustration. 2 is sectional elevation of the device taken on the line:vrc of Fig. 1.

Tlhree segmental saws 1 of steel are provided at their inner sides withconcave toothed edges 2, whereby together they constitute one circularsaw or ring the inner periphery of which serves the cutting edge. Thesegments 1 are seated upon a circular ing or frame 3 of suitable material having a tapped rim st, and a ring threads into said rim andagainst a ledge 6 of frame 8, leaving a space 7 within which saidsegments are retained. Pins 8 secured to the frame pass throughelongated guiding slots 9 in the segments 1, whereby the segments arecapable of being guided and moved in their retaining space 7 toward andaway from the center of the device. Leafsprings 10 secured at one end 11to the rim r of frame 3 bear against the outer edges 12 of the segments1 and thereby press the segmentstoward the center of the device, theends of guiding slots 9 abutting against the pins 8, as shown, andlimiting the inward movement of the segments. A flexible circular bar13, preferably of metal, passes throu h e es 14 secured to the segments1 and its extremities 15 terminate at a meeting place 16 between two ofsaid segments. Through an opening 17 in rim 4 passes a stem 18 providedat its extremity outside of the rim with. a thumb-head 19 and at itsopposite end with. a cone-portion 20 located between the terminals 15 ofthe bar 13. A spring 21 wound around the stem 18 and secured to the rim4 and to the cone 20 normally draws the stem outwardly and maintainssaid cone in the position shown. Upon pressing of the stem 18 byapplying the thumb against its head 19 the cone 20 is moved inwardly andcaused to bear against the bar-terminals 15 and to spread the circularbar 13 in such manner as to increase its general diameter, whereby thesaws or segments 1 are in turn caused by said bar to spread apart fromeach other and to simultaneously move away from the center of the devicewith which they are concentric.

The inner and under sides of the ring 3 are beveled and formed, as shownat 21, to follow the configuration of the egg, and by this means theentire device may be conveniently seated upon the wide end 22 of the egg23, indicated in dash and dot lines, Fig. 2. Preferably a rubber ring 2is inlaid within the beveled portion 21 to afford firmer seating of saidportion against the shell of the lVhen it is desired to open a boiledegg the device is first seated on the egg in the manner shown, andthereupon the frame 3 may be gripped and rotated partially in oppositedirections. This operation causes the toothed edges 2 of saws 1 toproduce a complete circular cut around the end of the egg and to therebysever a circular portion 24 of the shell from the remainder of theegg-shell. The thumbhead 19 may be then pressed to move the toothedcutting edges 2 away from the center of the device and out of the'cut inthe egg shell, in which manner the saws 1 completely clear the shell sothat the device may be thereupon conveniently removed from the egg.After thus producing the cut in the egg shell and removing the devicethe severed shell-pon tion 24: may be readily lifted and removed, andthe circular opening left in its place may be utilized for inserting aspoon therethrough and removing the egg-contents.

It will be evident that by the utilization of this device boiled eggsmay be convenientlv and readily-opened, by those serving them or by theuser at the dining table, and the insanitation resulting frequently fromthe fingers coming in contact with the egg contents and the many otherwell known )ressin its saw toward the center of said frame.

2. A device for opening eggs having the combmatlon of an annular frame,a plurality of saws within said frame adapted to be placed over aportion of the egg,

a spring for each of sald saws pressing it toward the center of saidframe, and means to move .all of said saws apart contrary to thepressure of all of said springs.

3. A device for opening eggs having the combination of an annular frame,a plurality of saws within said frame adapted to be placed over aportion of the egg, means for guiding each of said saws toward and awayfrom the center of said ring, and a spring for each of said sawspressing it toward the center of said frame.

4:. A device for opening eggs having the combination of an annularframe, a plurality of saws within said frame adapted to be placed over aportion of the egg, a spring for each of said saws pressing it towardthe center of said frame, a flexible bar connecting said saws, and astem adapted to press against the ends of said bar to move all of saidsaws simultaneously contrary to the pressure of their springs.

5. A device for opening eggs having the combination of an annular frame,a plurality of saws within said frame adapted to be placed over aportion of the egg, means for guiding said saws toward and away from thecenter of said frame, a spring for each of said saws pressing it towardthe center of said frame, a bar connecting said saws, and a stem adaptedto press against the ends of said bar to move all of said saws contraryto the pressure of all of said springs.

6. A device for opening eggs having the combination of an annular frame,a plu- .ality of saws Within said frame adapted to be placed over aportion of the-egg, means automatically pressing said saws toward thecenter of said frame, and means to move said saws apart contrary to saidpressing means.

7. A device for opening eggs having the combination of an annular frame,a plurality of saws within said frame adapted to be placed over aportion of the egg, a spring for each of said saws pressing it towardthe center of said frame, and a spring-pressed stem mounted on saidframe adapted to press all of said sawsapart contrary to the pressure ofall of said springs.

Signed at the city of New York, in the county of New. York, and State ofNew York, this 9th day of November, A. D. 1915.
